Check Shopify's managed default first
Shopify already manages /agents.md for every store; /llms.txt and /llms-full.txt mirror it by default. For most stores, keep that managed default. An existing file is not evidence that a separate app or custom template is needed.
- /agents.md is the canonical agent-discovery document
- /llms.txt and /llms-full.txt mirror it by default
- An app is not required merely to make these URLs exist
